Lead Screw Nuts

Lead Screw Nuts

Mate with lead screws to move components in a straight line

Ball Screws and Nuts

Ball Screws and Nuts

Internal ball bearings roll on screws for low friction when moving components at high speeds

Stepper Motors

The motor shaft turns in small, equal increments for precise positioning

Roller Screws and Nuts

Roller Screws and Nuts

More contact points to move heavier loads than ball and lead screw assemblies

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Material Handling

Robot Bases

Elevate robot arms so they can reach raised surfaces, such as conveyor belts and workstations

Robot Vacuum Lifters

Robot Vacuum Lifters

Use suction to grip, lift, and move objects with a robot arm

Vacuum Cup Levelers

Vacuum Cup Levelers

Adjust vacuum cups to lift items with variable heights; also known as spring plungers

Vacuum Lifter Dampers

Vacuum Lifter Dampers

Stick onto vacuum lifters to create a soft surface for moving delicate parts

Vacuum Lifter Accessory and Replacement Parts

Vacuum Lifter Accessory and Replacement Parts

Add accessories such as sensors or replace cups and other parts on your vacuum lifter

Vacuum Fittings

Vacuum Fittings

Connect to vacuum cups and compressed air to create suction; also known as venturi devices

Vacuum Pads

Add to vacuum cups to move textured items that standard cups can’t pick up

Raw Materials

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing
